Oculus Rift: Best ways of protection for daily usage?

we have a project where an Oculus Rift will be used up to a 100 times per day over several months. By kids. So you see, there is a lot of potential these glasses break. We're thinking about a hardware solution such as a protection case for the glasses, and therefore I wanted to ask here, if anybody knows an existing solution?

The goal must be that it is still very simple to use the rift, but it should also be ready for such heavy usage.
